Abstract
An acousto-optic system is provided that has an acousto-optic device coupled to a DDS IC controller. The DDS controller provides amplitude modulation to adjust output power synchronously with changes in frequency when activating a different frequency.
Claims73
An acousto-optic system, comprising:
- an acousto-optic device;
- a DDS controller coupled to the acousto-optic device, the DDS controller providing amplitude modulation to adjust output power synchronously with changes in frequency when activating a different frequency profile.
An acousto-optic system, comprising:
- an acousto-optic device;
- a DDS controller coupled to the acousto-optic device;
- and
- wherein the DDS controller includes at least a first DDS IC and a separate circuit that tracks a user's request to directly frequency modulate the DDS IC.
